Brazil has pledged to reduce its greenhouse gas emissions by 37 per cent by 2025 from 2005 levels as part of its contribution to a pact to fight global warming.
President Dilma Rousseff announced Brazil's targets for a landmark agreement on climate change in an address to the UN in New York on Sunday.
In addition to its 2025 commitment, Rousseff said Brazil has an "ambition" of achieving 43 per cent emissions reductions by 2030.
Brazil intends to reach those goals by boosting renewable energy sources including solar, wind and biomass and continuing to reduce deforestation in the Amazon region.
The World Resources Institute, an environmental think tank, says Brazil's emissions fell about 36 per cent between 2005 and 2011 primarily due to efforts to reduce deforestation, a major emissions source in Brazil.
